What levels of protein structure would be affected if all hydrogen bonding interactions were prevented? check all that apply?
fgiga [73]

The proteins exhibit four levels of organization:  

1. Primary structure: It refers to a sequence of amino acids join together by the peptide bonds to produce a polypeptide chain.  

2. Secondary structure: It is a localized twisting of the polypeptide chain by producing a hydrogen bond. Two types are formed, that is, the alpha helix and beta pleated sheet.  

3. Tertiary structure: It refers to the three-dimensional composition of a polypeptide chain. The folding is not regular as it is in secondary composition. It produces ionic bonds, hydrophobic interactions, disulfide bond, and hydrogen bond amongst the polypeptide chains.  

4. Quaternary structure: It comprises an amalgamation of two or more polypeptide chains that functions as a single functional unit. The bonds are identical as in tertiary composition.  

Thus, the levels of secondary, tertiary, and quaternary protein structure would get affected if all the hydrogen bonding associations were inhibited.

How is ATP created in photosynthesis?
uranmaximum [27]

Answer:

The correct answer is option e, that is, a, b and c.  

Explanation:

The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.  

With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.
